4253 5517 d 17 h decky /trunk/uspace/ make klog more generic  
4241 5518 d 16 h svoboda /trunk/uspace/ NS was forgetting to hangup phones. One phone was leaked for every load attempt and when all 16 phones were exhausted, NS would lock up.  
4008 5552 d 19 h decky /trunk/uspace/srv/ns/ add support for pending (blocking) connections to services
cleanup & cstyle		  
3908 5566 d 18 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3904 5567 d 15 h svoboda /trunk/uspace/srv/ns/ Careful, call must be copied by value in ns.  
3896 5568 d 13 h svoboda /trunk/ More elegant way of invoking the loader - as a 'cloneable' service. Task names functionality lost for the time being.  
3083 5824 d 22 h decky /trunk/uspace/srv/ns/ service banner  
2677 5979 d 20 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.		  
2637 6006 d 17 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2635 6008 d 17 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.		  
2622 6016 d 23 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.		  
2619 6020 d 15 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().		  
2594 6035 d 16 h cejka /trunk/uspace/ New version of device mapper.
Added devmap test to tester.		  
2588 6037 d 22 h jermar /trunk/uspace/ Add ipc_answer_fast_[01] macros so that ipc_answer_fast() users don't have to
write zero arguments all the time.		  
2479 6170 d 23 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2476 6173 d 16 h jermar /trunk/ Cleanup.  
2471 6176 d 17 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2141 6258 d 13 h jermar /trunk/ The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.

Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.		  
2071 6327 d 16 h jermar /trunk/ (c) versus (C)  
2015 6366 d 17 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.
